In this paper, Bertrand and coworkers describe a beautiful new type of compound: a singlet phosphinonitrene, where the phosphorus is stabilized by two imidazolidin-2-iminato groupsThough not air-stable, Dielmann et al. succeeded in isolating, crystallizing, and characterizing it spectroscopically.  They also showed its utility in N-transfer.
